Image wipe method and device

Abstract

An image wipe method includes the steps of defining at least a first reference point to divide a screen area into several sub-areas according to the first reference points, selecting at least one sub-area, and performing a first image process on the selected sub-area. In addition, an image wipe device for executing the method is provided.

1. An image wipe method, comprising:
 defining a first reference point to divide a screen area into a plurality of sub-areas; 
 selecting at least one of the sub-areas; and 
 performing a first image process on the selected sub-area, wherein the first image process is to display a first picture. 
 
   
   
     2. The method of  claim 1 , further comprising:
 performing a second image process on the unselected sub-areas. 
 
   
   
     3. The method of  claim 2 , wherein the second image process is to display a second picture. 
   
   
     4. The method of  claim 1 , further comprising:
 defining a second reference point to divide the screen area into a plurality of sub-areas according to the first reference point and the second reference point. 
 
   
   
     5. The method of  claim 4 , wherein the first reference point and the second reference point are custom-defined. 
   
   
     6. The method of  claim 4 , wherein the first reference point comprises a first horizontal coordinate and a first vertical coordinate, and the second reference point comprises a second horizontal coordinate and a second vertical coordinate. 
   
   
     7. The method of  claim 1 , further comprising:
 setting an area code for each of the sub-areas respectively, wherein the area code is for indicating the sub-areas to display corresponding images. 
 
   
   
     8. The method of  claim 7 , further comprising:
 comparing the first reference point and at least one counter value to set the area code. 
 
   
   
     9. An image device, comprising:
 a reference point defining module, which defines a first reference point; 
 an area dividing module, which divides a screen area into a plurality of sub-areas according to the first reference point; 
 a selecting module, which selects at least one of the sub-areas; and 
 an image processing module, which performs a first image process on the selected sub-area, wherein the first image process is to display a first picture. 
 
   
   
     10. The device of  claim 9 , wherein the image processing module further performs:
 a second image process on the unselected sub-areas, and the second image process is to display a second picture. 
 
   
   
     11. The device of  claim 9 , wherein the area dividing module further comprising:
 an area code setting module, which sets an area code for each of the sub-areas respectively according to the first reference point and at least one counter value. 
 
   
   
     12. The device of  claim 11 , further comprising:
 a comparing module, which compares the first reference point and the counter value to output a result signal for composing the area code. 
 
   
   
     13. The device of  claim 11 , further comprising:
 a selecting module, which selects at least one of the area codes to retrieve the corresponding sub-area. 
 
   
   
     14. The device of  claim 11 , further comprising:
 a look-up table, which records the area code and a to-be-displayed image corresponding to the area code, wherein the image processing module accesses the look-up table to display the to-be-displayed image on the selected sub-areas so as to perform the first image process. 
 
   
   
     15. The device of  claim 9 , wherein the reference point defining module further defines a second reference point. 
   
   
     16. The device of  claim 9 , further comprising:
 a user interface, which is for a user to change the reference point and for the reference point defining module to custom-define the first reference point. 
 
   
   
     17. The device of  claim 9 , which is installed in a multimedia computer system or a digital versatile disk (DVD) playing system.
